The truth about Retr0brite – busting myths with science…

Video sponsor: PCBWay: $5 for 2-layer PCBs with 24hr turnaround at https://www.pcbway.com/ Chucks video:    • Hydrogen Retrobright Experiment   One of the situations we are often faced with when restoring an old computer is a yellowed plastic case. You have probably heard of Retr0Brite, few things in the retro community have caused as much controversy, rampant speculation and unfounded opinions as this subject. While there has been a lot of speculation and theories passionately bandied about on this subject there has not been an effort to understand the process. A combination of research and practical experimentation was done to try and answer the questions: What it is Retr0Brite doing and what is it doing, or not doing, to the plastic. We will discover where color comes from, what plastic is, what makes plastic yellow, and what Retr0Brite is actually doing. This video is the result of an effort to get to the bottom of the matter using a scientific approach. I ask that you please keep an open mind and watch through to the end of the video before banging out a comment on your keyboard.
